My 12month old min-pin passed away on April 5th. He had a adverse reaction to an immunity booster shot which was given to him twice, and had a total of 4-vaccines by the time he was 9wks. He developed a lg bump behind his left upper shoulder which later turned into Melenoma sarcoma. I always felt the vaccine caused this, because he yelped after the final shot, and a day later it turned into a hard lump, and 2-months after turned into cancer. We tried every method to save his life, but all that did was buy him time. I want to know what these vaccines contain, and why he had to have so many?

Last year when I took our cats for their vaccinations ( rabies, feline leukemia, distemper). Right after we got home. Our six year old cat, Fuzzy (American short haired orange and white tabby, neutered), had a severe allergic reaction to them. He was vomiting every few minutes and panting , and shaking and then started having diarrhea; all at the same time. We had been the last appointment of the day so our vet was closed. We rushed Fuzzy to the emergency clinic where they told me that it was not uncommon for a cat to have a reaction to a vaccine that they may have had before with no bad reaction. They gave him steroids and fluids intravenously, and he survived. Today, with much trepidation I took the cats for their annual vaccinations. My new vet gave fuzzy his shots along with a shot of benedryl, and some prednisone tablets to take home with me for him just in case. They told me also that I could bring him right in if he had a bad reaction. He is fine. However our 18 month old cat, Twinkie ( neutered male american shorthair cream and white tabby) is having a reaction this evening. He received rabies, distemper, and feline leukemia vaccines. He is feverish, lethargic, doesn't want to be picked up or have his abdomin touched ,and won't eat or drink. I will be up tonight monitoring him , and may have to take him to the emergency vet.

My 7 year old lab had a severe reaction to a seven way vaccine. I gave him the shot and within 5 minutes he had collapsed in the yard. I rushed him to the vet where he recieved 2 shots of eperinephinand a steroid shot (in less than 30 minutes from the origional shot). the vet had checked on him an hour later he showed some activity. When the vet returned two hours after that he was dead. This was the same shot I had been giving him for seven yrs, just this time it was fatal.

We have 4 miniature dachshunds. They had their 5 in one annual vaccine plus a rabies shot. All 4 of them had severe swelling, itching and disorientation reactions. 2 of them vomited. They had cortisone to ease the reaction. The vet said it happens to one dog in a thousand. So how come in our case it was 4 out of 4? Sad Truth is most (not all) vets and the health authorities do not care about the short term and long term side effects of the poison vaccines injected into our beloved animals. Of course it is difficult to pinpoint a long term side effect - but given the immediate horrid short term effects, there must surely be negative long term side effects as well.

My poodle was vaccinated a few days ago and I also found two lumps on him. One of his shoulder and the other under his arm. The one under his arm doubled in suize in less that 24 hours but then disappeared. If these are normal side efects, why wasn't I told by the vet or the groomer (had him groomed that day too). I have been freaking out all weekend. I found my dog a year ago and this is 1st time I got him vaccinated and they knew that. I am sad and very scared right now.

More sad news about vaccinations? I had my 4 year old Norwich Terrier vaccinated for DHPP and Leptospirosis in December per our "regular" plan with our vet. Clancy was a spunky energetic dog.Three months later, in early March Clancy became lame in his right front leg. We initially thought it was just a leg injury but, it turned out he had cancer. Three heartbreaking months and thousands of dollars later we had our be-loved dog put to sleep. We didn't know about the risks of over vaccinating. With a heavy heart and a hole in our lives we won't make the same mistake again.

My dog just got vaccinated yesterday too. She had the exact symptoms. I coult'nt even touch her, she was in so much pain. She couldn't go down the stairs to pee and couldnt get confortable. She was sleeping standing up. Her tongue felt really warm, I'm sure she had a fever. This morning she is 80% back to normail. I think your dog should be seen by a vet asap. Three days with no improvment is too long. Good Luck

i took my 2 year old boston terrier to get his vaccinations this week. he was very sore and cried when i tried to pick him up.he was also not putting any pressure on his back leg. i spoke to the vet and they said it was common. i'm worried because it has been 3 days and he is still lethargic and looks sad. he has not interest in playing. i'm wondering how long these side effects will last?

My dog went for a recheck for his anal gland infection and was cleared to get a booster of DHLPPC, rabies and Bordetella. He ended up vomiting multiple times within 48 hours. He is a Tibetan Mastiff and 17 months old.

My Chi just went in yesterday for his 3 yr rabies and his distemper shot. He had a bad reaction that last time this occured and I told the vet. I said I was afraid he was given to much. The vet says its one size fits all, so what they give a 100 pound lab they give my 7 lb chi. INSANE! My dog is again having severe reactions to these shots. He cant move he whines outloud. He whimpers. God forbid your touch his legs he cries out. They gave us a steriod which worked for a few hours and then wore off, I gave his another pill and it never touched his pain. I have tried Metacam now and still he just cries. I stayed up to 3 am with him last night. I want to know what can I do now and in the future can i say NO to the distemper shot, the county I live in makes us get rabies although I will get the 1 yr shot next time not the 3 yr. I cant even take him to the vet right now because to move him would cause him severe pain. This makes me sick!!!

our soon to be 4 year old jack russell (female-spayed)went for her yearly dhlppv booster. we had recently moved & also recently lost our long time vet. we searched and found a new vet in our area. without giving us the option, he examined her, verified her recent rv vaccination & then proceeded to pull up the dhlppv injection & then without asking or warning he proceeded to give her the kennel cough vaccine (intra-nasal). we were not allowed to hold her so were blocked from effective seeing what he was doing until he was doing it, when he stated that since she saw a groomer once a month (same one since she was 4 months old) she had to have the vaccine. within 48 hours she started with the horrible cough & throwing up mucous. we called the vet but were made to feel like we were bothering them. we have searched online & found some help & are giving her benadryl twice a day & keeping her quiet. it is coming up on a week now & she is not much better. anyone have any suggestions? besides never using that vet again!?!?!

I'm posting to share my cat's vaccination experience earlier today. his name is Biff- he's a 5 year old lynxe point siamese-he's big-16lbs-but not really overweight-maybe just a tad. Took him to the vet at 5:30-already worried and not feeling quite right about allowing him to be vaccinated- he had a rabies on left shoulder & respitory & luekemia combined on the right shoulder. Then we had my dogs nails trimmed- we were on our way out the driveway around 6 when I heard him vomit-back to the vet. She at first thought overexcitement, but he continued to vomit & she agreed he was having a reaction & injected benadryl. And then we watched him. He was still vomiting every 5 minutes or so. He was licking at the injection site alot throughout the next couple of hours- where he got the rabies- and trying to reach it with his back paw to scratch- he chewed on the pads of his feet a few different times- he was very agitated and obvoiusly experiencing quite a bit of discomfort. His fur on his back kept twitching on and off- like he's trying to shake off the feeling - wouldn't still for long kept pacing- was panting openmouthed a few times. The vet after about 45 minutes of this gave him a steroid shot. We waited another half hour til he seemed well enough to go home & hadn't vomited in about 25 minutes or so. The vet seemed very surprised that it was a rabies reaction-said it was really uncommon. On our way home he lost bladder conrol in his crate. He's been better since we've been home- he's pretty sleepy- I'm just worried something more will happen tonight- don't want to fall asleep in case. this sucks- This very much worsens my concerns about vaccinating- I feel lucky after reading some of the other stories that the end result wasn't death.
